The FLEXTRA Run Editor
Flextra Exe Path
...
Specifies how the input data path is specified. The possible values are path and icon. When it is set to path we will specify the input data files and the AVAILABLE file by their paths. While in icon mode the input data is specified by a FLEXTRA Prepare icon in FLEXTRA Flextra Input Data. The default value is path.
...
Specifies the location of the AVAILABLE file using. The default is SAME_AS_INPUT_PATH, which mean means that the AVAILABLE file is located in the same directory as the input data. Enabled when Flextra Input Mode is path.
...
Specifies the run mode for the FLEXTRA simulation. THe The possible values are as follows:
- In normal mode, a group of trajectories is specified starting from the same point but at different times. Several starting points (thus several groups of trajectories) can be defined for a single FLEXTRA run.
- In cet mode, trajectories are generated starting from the points of a user-defined uniform grid in a three-dimensional domain.
- In filight flight mode, both the starting location and starting time for each trajectory can be set individually. This mode is useful to calculate e.g. trajectories released along the flight track of an aircraft.
The default value is normal.
Flextra Trajectory Direction
...
Specifies the list of trajectory types as numerical IDs when Flextra Run Mode is set to normal. The possible values are as follows:
| Numerical ID | Description |
|---|---|
| 1 | 3 dimensional |
| 2 | model level |
| 3 | mixing layer |
| 4 | isobaric |
| 5 | isentropic |
The default value is 1 (three-dimensional trajectories).
...
Specifies the level types (as numerical IDs) of the trajectory start points when Flextra Run Mode is set to normal. The possible values are as follows:

| 2 | Metres above ground level |
| 3 | hPa |
The default value is 1 (metres above sea level).
...
Specifies the list of trajectory type as numerical IDs or strings when Flextra Run Mode is set to cet. The possible values are as follows:

| 4 | isobaric |
| 5 | isentropic |
The default value is 1 (three-dimensional trajectories).

| 2 | metres agl | Metres above ground level |
| 3 | hPa |
The default value is 1 (metres above sea level).
...
